查看样本合金摘要数据表（PDF）自1952年以来，合金摘要一直是世界各地使用的金属和合金材料性能数据的主要参考。这些图表和可加工性、图表和热处理图表和图表。TOPHET合金A长期以来一直被用于适用于2150华氏度（1175摄氏度）的电阻加热元件。耐化学腐蚀和渗碳环境拓宽了该合金的应用范围。本摘要取代了2/58的备案代码Ni-39。

View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.TOPHET Alloy A has long been used in resistance heating elements serviceable to 2150 F(1175 C). Resistance to chemical corrosion and to carburizing atmospheres broaden the alloy's range of applications. This Digest supercedes Filing Code Ni-39 of 2/58.
